Energy - KE & PE
Moving energy is called this
Kinetic
This is the transfer of thermal energy by contact between two things
CONDUCTION
The top part of a wave
crest
This action is needed to close an open circuit
CLOSE SWITCH/CONNECT WIRES
The strongest magnetic force comes out of these in a magnet
POLES
This type of renewable energy comes from the sun
Solar
This is the formula for calculating kinetic energy
KE=.5mv2
Wood is an example of these types of materials that don’t transfer heat easily:
INSULATORS
The name for the substance that carries sound waves
Medium
This variable in Ohm’s law is the one that pushes the current through
Voltage
Opposite poles do this in magnets
Attract
This type of renewable energy comes from the heat within the earth
Geothermal
The type of potential energy stored in hanging monkeys
Gravitational Potential Energy
This measures the average kinetic energy in a substance
Temperature
This is the number of waves passing a point in a certain amount of time
Frequency
This device provides the voltage in a circuit
Battery
Like poles do this in magnets
Repel
This type of renewable energy comes from damming rivers
Hydroelectric
This device converts chemical potential energy to electrical kinetic energy
Battery
These are formed due to changing densities among fluids
Convection currents
When the frequency of a wave increases, this decreases
Wavelength
When you increase the resistance in a circuit, this decreases
Current
This is a naturally magnetic metal with symbol Fe on the periodic table
Iron
The burning of these contributes to the rapid global climate change
fossil fuels
The cannonball has a mass of 40kg and velocity of 250m/s. The energy of the cannonball is
1,250,000 J
Thermal energy is transferred from the sun to earth using this method of heat transfer
Radiation
The wave has a speed of 35 m/s and a wavelength of 0.3 m. The frequency of the wave is
10.5 Hertz
The circuit has a resistance of 2 ohms and a current of 1 A. The voltage is…
2 Volts
When these align, an object can become temporarily magnetized
Domains
Methane and this greenhouse gas are the most common gases emitted from burning fossil fuels
Carbon Dioxide CO2
